Description

TECHNICAL FIELD [0001] The present invention relates to a method for manufacturing a reflective body,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a three-dimensional reflection harmony through a mold, and more particularly, And more particularly to a method of manufacturing a reflex harmony through a mold mold of a new type having an excellent preventive effect.

Generally, various safety signs having a retroreflective function are installed on the roads of automobile roads or highways in order to provide safe driving of the driver in preparation for nighttime or overcast weather.

As a conventional technique in this field, Korean Patent Application Publication No. 10-2010-0049444 (published on May 12, 2010) discloses a technique relating to a road fence as a road sign having a reflex reflection function. However, these roadside fences are flat and not aesthetically pleasing, but only for retroreflective function and original fence applications.

As such, almost all of the road sign products currently on the market have a retroreflective function.

Retroreflective refers to the reflection of light from a light source on the surface of an object with a recursive reflection function (for example, a road sign) and then back to the light source. Reflects light in the direction of the light source even if it is illuminated by a retroreflective material (eg, a road sign) at any angle. That is, when a headlight or a flash light (light source) of a vehicle as a light source is reflected on a retroreflective material (for example, a road sign), the person in the light source can easily see the retroreflective material.

However, most products which facilitate the safe driving of the vehicle by facilitating the identification of the road at night such as the road signs nowadays, for example, the reflector reflector reflector, etc., are flat. Therefore, there is a limit to the angle of reflex reflection depending on the installation state of the road sign, which is a limitation in exerting the reflex reflection effect.

In addition, a conventional road sign or a safety sign has a purpose to provide a retroreflective function, but it has a problem that it hurts aesthetics and hinders the sight of surrounding facilities.

On the other hand, there is a demand for a technique that can obtain a retroreflective function in all directions while considering aesthetics.

There is a lot of harmony in the center of the road, and there are some signs of reflex reflection. The harmony that is planted on the median separator is used instead of the limitation that it can not be preserved for a long time because it is easily wilted.

However, in the nighttime, a safety sign having a retroreflective function can not be seen, so a countermeasure is also required.

An object of the present invention is to provide a method of manufacturing a three-dimensional reflection harmony through a new mold mold which is well visible in nighttime and weekly overcast weather while serving as a road sign and at the same time having a good visual appearance.

Another object of the present invention is to provide a method and apparatus for coating a reflective pigment on a surface of a roughened surface by applying a reflective pigment to roughened surface by a silk screen method and then applying a three- And a method for manufacturing the same.

It is another object of the present invention to provide a method of manufacturing a three-dimensional reflection harmony through a mold mold, in which a specific pattern is directly formed on a fabric by a high-frequency welding process using hot melts and then a three- .

It is another object of the present invention to provide a method of manufacturing a three-dimensional reflection harmony through a mold die in which a work process is improved so that a large amount of reflection harmony can be produced.

The above objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention by those skilled in the art.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and the manner of achieving them, will be apparent from and elucidated with reference to the embodiments described hereinafter in conjunction with the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. And the present invention is defined by the scope of the claims. Like reference numerals designate like elements throughout the specification.

Hereinafter, a method for manufacturing a three-dimensional reflection harmony through a mold metal according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a flowchart schematically showing a method of manufacturing a three-dimensional reflection harmony through a mold metal according to an embodiment of the present invention.

In order to manufacture the reflection harmony according to the present invention, a fabric is first prepared. Fabrics used for reflex harmonization may include fibers such as thin cotton, cotton, billet, silk, satin, dexin, poplin, and ogundi. In some cases, paper such as Korean paper, non-agricultural paper or crepe paper may be used, or leather such as sheepskin or cowhide may be used. A polyester-based material may be used as the reflective harmony fabric.

The reflection harmony produced by the method of manufacturing the three-dimensional reflection harmony through the mold according to the present invention is a combination of the real harmony of reality and the creative harmony that is created regardless of actualization and the creativity of the artist And / or < / RTI >

In the present invention, the reflex harmony is intended to be used for a road sign or a median separator. However, the reflex harmony can be used for various purposes such as a headdress, a breast, a hat, a decoration for a house, . It is of course also possible to be used in all fields for the purpose of reflex reflection.

When the fabric is ready, the prepared fabric is cut to a size suitable for producing the fabric (S110). In the present invention, the cloth can be cut to a size suitable for screen printing, and cut to a size of, for example, 150 cm in width and 90 cm in length.

When the fabric is ready, a reflective pigment to be applied to the surface of the blend is prepared (S120). In this embodiment, the reflection pigment is prepared after the cut of the fabric, but the process order of the cut of the fabric and the production of the reflective pigment may be reversed.

The reflective pigment is produced by mixing a reflective material (for example, glass beads) that directly reflects light received from the outside and a screen printing ink that prints the reflective material through screen printing and adheres to the surface of the fabric.

The screen printing ink may be a solvent ink or a UV ink. The solvent ink is characterized in that it is volatilized and dried at room temperature or in a heated state, and UV ink is dried by ultraviolet rays. UV ink can be instantly dried under ultraviolet light at a high temperature, so that the surface can be smoothly printed and a product with good endurance can be obtained.

The reflective pigment according to an embodiment of the present invention can be produced by mixing the reflective material at a ratio of 50 wt%: 50 wt% with respect to the weight of the screen printing ink. It is possible to obtain a retroreflective effect of desired brightness by controlling the weight ratio of the screen printing ink to the reflective material.

Here, in the reflective pigment, the size of the reflective material particle may be formed into a powder having a size in the range of 1 to 4 mu m. This is because when the screen material is printed, the reflective material particles smoothly penetrate the screen net such as silk, .

In the present invention, the ratio of the reflective material to the screen printing ink may be 50 wt%: 50 wt%. However, the present invention is not limited thereto. By using such a reflective pigment, the retroreflective effect can be maintained almost permanently.

On the other hand, the ratio of the reflective material to the screen printing ink may be various ratios such as 70wt%: 30wt%, 80wt%: 20wt%, 60wt%: 40wt%, 40wt%: 60wt%, 30wt%: 70wt%

The reflective material is made of, for example, glass bid (glass beads). However, it is not limited thereto, and the reflective material may include other materials having a retroreflective effect. For example, a pigment of a specific color (eg, gray, white, etc.) can be added to the glass bead to enhance the reflex effect.

When the production of the reflective pigment is completed, the reflective pigment is applied to the front surface of the fabric through screen printing (S130). At this time, as shown in FIG. 2, the screen printing machine may have a plurality of air holes 25 formed in the support plate 20 of the screen printing table 10. A fabric (not shown) is placed on the support plate 20, and the screen 30 is placed on top of the fabric.

The screen printing process involves applying a reflective pigment onto the screen 30 and pressing the top surface of the screen 30 with the squeegee 40 to cause the applied reflective pigment to pass through the screen 30 and into the screen 30, A vacuum pump (not shown) for sucking air is provided in the printing table 10 and an air hole 25 formed in the receiving plate 20 is connected to the vacuum table The air on the upper portion of the print table 10 can be sucked into the lower portion of the print table 10.

Air in the upper portion of the fabric is sucked downward through the air holes 25 of the support plate 20 placed under the fabric. When the air is sucked into the lower portion of the fabric, the reflective pigment applied to the fabric can be uniformly applied to the entire fabric, and the reflective pigment can be more easily adhered to the fabric, thereby reducing the drying time after the application of the reflective pigment. Therefore, the time of the whole process can be shortened.

At this time, the fabric may be water-repellent or water-repellent before the application of the reflective pigment (S130). The waterproofing or water repellent treatment step may include a step of applying a waterproofing solution or a footing solution to the fabric and a step of drying the fabric to which the waterproofing solution or the footing solution is applied. If the fabric is not waterproof / water repellent, the reflective pigment can penetrate through the fabric and flow out through the air hole 25 to the lower portion of the printing table 10, and the air hole 25 is clogged by the reflective pigment There may be a problem of By applying the reflective pigment to the waterproof / water-repellent fabric, it is possible to prevent the reflective pigment from permeating through the air hole 25 or blocking the air hole 25.

The screen printing may be carried out through silk screen printing or printing. Silk screen printing is performed by disposing a fabric on the lower surface of a silk screen, arranging a pattern corresponding to the shape of the petals on a silk screen, Is applied through a squeegee to allow the reflective pigment to penetrate the silk web and print on the surface of the fabric.

In printing, a portion other than the content to be printed is covered with paper, and the reflective pigment is extruded through the screen to be printed on the surface of the fabric.

Silk screen printing or printing may be selected depending on the size of the harmony and the shape and color of the harmony.

When printing of the reflective pigment on the front side of the fabric is completed, the fabric is dried so that the reflective pigment is completely adhered to the front side of the fabric (S140). If the reflective pigment is a mixture of UV inks, the fabric may be exposed to ultraviolet light in an environment of about 200 캜 to dry. UV inks can be dried quickly in high temperature ultraviolet light and can be dried quickly and the printed surface of the fabric can be smoothly dried.

When adhesion of the reflective pigment to the front surface is completed, a reflective pigment is printed on the rear surface of the fabric through screen printing (S150). After the reflective pigment is printed on the back surface in the same manner as the front surface, the fabric is dried so that the reflective pigment is completely adhered to the rear surface of the fabric (S160).

On the other hand, screen printing can be done only on the front side and not on the front side and rear side if necessary. This is an option for mass production or user choice.

When the application of the reflective pigment to the fabric is completed, petals forming harmony are punctured at the fabric (S170). A plurality of petals are pierced from a fabric using a piercing mechanism (not shown) such as a press, and then the petals are transferred to the upper and lower molds to form a three-dimensional shape in order to make the petals into a three- (S175). In such a molding process, a silicone release agent is injected together to easily remove the stereoscopic harmony that is completed after the molding, from the mold.

The above process will be described in more detail with reference to FIGS. 5 to 9. FIG.

In order to fabricate the reflex harmony, the fabric is generally cut into flower shape, and the fabric is pressed with the mold (the upper part is made of aluminum) You have to press it to get a flower shape.

However, there is an adhesive component in the solvent screen ink used when mixing fabric with reflective pigment to fix the reflective pigment on the fabric to the fabric when the fabric is heated at a temperature of 200 ° C or higher. To solve the problem, silicone can be sprayed onto the mold mold and pressed to form a silicone film on the mold, allowing the solvent screen ink to work without sticking.

Thereafter, the completed three-dimensional petals are collected to form a harmony (S180).

At this time, the lower part of the petal is fixed with a fixing tool such as a wire, the upper part is formed into a shape to form a harmony, and the pedicel is completed, and the stem is connected to the lower part of the pedicel to complete the production of the reflex harmony . At this time, depending on the kind of harmony, wire, ribbon, flower seed, etc. may be used.

It is also possible that the fabric of the initial roll type is waterproofed and the reflective pigment is processed without screen printing or cutting process in the process of producing the above-described reflection harmony. In this case, the perforation process is performed before the forming process, and then the process of producing the three-dimensional blend is the same.

Although white reflective pigments are used in the present invention, gray pigments can be used if necessary. This can be a user choice for the application and there is little difference in the effect of recursive reflection.

FIG. 3 is a photograph of the reflection harmony produced by the method of manufacturing a three-dimensional reflection harmony through a mold mold according to the present invention.

As shown in the photograph, the reflection harmony according to the present invention is characterized in that the reflective pigment is uniformly applied to all the petals and the shape of the petals is three-dimensionally formed in the course of the molding, It is possible to provide a retroreflected light to the driver.

As shown in FIG. 3, when dozens or hundreds of reflection harmonies are collected to form a flower bed at the roadside median or side, it is possible to provide a recreational use function and a cosmetically colorful median separator as a flower bed, (See FIG. 4).

Here, in the method of manufacturing the three-dimensional reflection harmony through the mold, the reflective pigment is printed on the fabric, and then the pigment is shaped into petals and subjected to a molding process to form a three-dimensional shape. In some cases, The valve may be removed in the form of a petal so that only the petal portion is printed with a reflective pigment. In other words, it is also possible to print a reflection pigment on the whole front surface of the quadrangle and then perforate the shape corresponding to the shape of the petal, or to print the shape of the petal on the square pattern with reflection pigment,

The above two methods can be selectively used depending on the size and shape of the petals.

In the method of manufacturing a three-dimensional reflection harmony through the mold of the present invention, the reflective pigment is applied to the fabric through screen printing. Accordingly, the reflective pigment can be evenly applied over the entire surface of the fabric. Since the reflection pigments are applied to the front and back surfaces of the fabric, the reflex reflection angle can be maintained evenly at any angle when forming the reflection harmony.

In addition, since the reflective pigment is applied to the fabric through the screen printing method instead of the spraying method through the spray, the working efficiency can be improved. Therefore, mass production is possible and manufacturing cost can be lowered, so that the spread of reflection harmony can be increased.

In addition, in the method for producing a three-dimensional reflection harmony through the mold metal of the present invention, a reflective material having fine-sized reflective material particles is used for producing a reflective pigment, and a mixing ratio of the reflective material is 50 wt% 50wt%, and the adhesion of the reflective pigment thus prepared was improved and the effect of retroreflection was enlarged.

In another embodiment of the present invention, a reflective material, a so-called glass bead, may be subjected to a heat fusion process or a high frequency welding process using hot melt instead of the screen printing method. The glass bead can be partially processed only in a specific shape, for example, a heart-shaped rim, and it can also have a reflex reflection effect.

Also, the reflective material is gray and white. In particular, gray has the best luminance (ie, retroreflective effect is the best), and the white effect is excellent.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.
